Materials used:
1: This board adopts a 2.0mm double-sided design, with a metal film of 1% error and high-precision Taiwan produced Kunmao coarse copper pin resistor. The load resistor is a Nissan KOA non-inductive power resistor, the film capacitor is a German Weima WIMA, and the electrolysis adopts Japanese ELAN and Nikon or Panasonic Fever capacitors. The power tube uses all new original Ansemy audio tubes (MJ15025 and MJ15024 tube king), with 8 pairs of 16 per channel. The excitation tube and voltage amplifier tube respectively use (MJE15035/15034 and MJE15033/15032) audio pair tubes, with neatly arranged components, reasonable circuit design, pure and sweet sound quality, and outstanding details. The sound is warm and smooth. Powerful and dynamic, usually large volume speakers can be pushed with ease
2. The integrated horn protection circuit on the board is provided separately and does not interfere with each other
